There's an Empires: Dawn of the Modern World Designer Diary #3 on GameSpy.com in which designer Rick Goodman outlines the task of creating the technology tree for Stainless Steel Studios' upcoming RTS. Also, there's a Civ III Conquest Designer Diary on IGN where Breakaway Games' Robert Waters discusses the creation of the Mesoamerican campaign in the upcoming turn-based strategy expansion.
